Vegetarian High-Protein Cottage Cheese Veggie Stir-Fry

Last Tuesday, my fridge held a wilting bell pepper, half a bag of frozen broccoli, and a tub of cottage cheese that was about to turn. Instead of ordering takeaway, I threw them all into a hot pan, and the result was so good I immediately made a second batch for the week. This Vegetarian High-Protein Cottage Cheese Veggie Stir-Fry is now my go-to for saving both money and time.

Why You’ll Love This Vegetarian High-Protein Cottage Cheese Veggie Stir-Fry

• Budget-friendly brilliance: At roughly £1.50 per serving, this dish proves you don’t need expensive cuts of meat or exotic ingredients to hit your protein goals. Cottage cheese and frozen vegetables keep costs low without sacrificing nutrition.
• Meal-prep champion: This stir-fry reheats beautifully, meaning you can cook once and eat well all week. The flavours actually meld and deepen after a day in the fridge, making leftovers taste even better than the first serving.
• Protein powerhouse: With nearly 30g of protein per portion, this vegetarian stir-fry rivals any chicken or beef dish. Cottage cheese is the unsung hero here, adding creaminess and a protein punch without any fuss.
• Customisable to your pantry: I’ve made this with whatever vegetables were on offer at the supermarket. Broccoli, bell peppers, carrots, courgettes, or even leftover green beans all work wonderfully, so you can adapt it to what’s in season or on sale.
• One-pan simplicity: There’s nothing worse than a recipe that leaves you with a mountain of washing-up. This comes together in a single large pan, meaning you can have dinner on the table and your kitchen tidy in under half an hour.

Ingredients You’ll Need

• 500g cottage cheese (full-fat or low-fat, your choice)
• 2 tablespoons olive oil
• 1 large onion, diced
• 3 cloves garlic, minced
• 1 red bell pepper, sliced into strips
• 1 yellow bell pepper, sliced into strips
• 2 medium carrots, julienned or thinly sliced
• 200g frozen broccoli florets, thawed
• 150g frozen peas
• 3 tablespoons low-sodium soy sauce or tamari
• 1 tablespoon toasted sesame oil
• 1 teaspoon ground ginger
• ½ teaspoon black pepper
• 2 spring onions, sliced, for garnish
• 1 tablespoon sesame seeds, for garnish

Tip: For the best texture, use full-fat cottage cheese if you can. It holds its shape better during cooking and adds a richer, creamier finish to the stir-fry. If you’re watching calories, the low-fat version works just fine, though the sauce may be slightly thinner.

How to Make Vegetarian High-Protein Cottage Cheese Veggie Stir-Fry

1. Prep your ingredients: Before you turn on the heat, have all your vegetables chopped and measured. This stir-fry comes together fast, and you won’t want to be scrambling to chop an onion while something burns. The cottage cheese should be drained slightly in a fine-mesh sieve for five minutes to remove excess liquid — you’ll notice it looks thicker and less watery.
2. Heat the pan: Place a large frying pan or wok over high heat and add the olive oil. Wait until the oil shimmers and you see the faintest wisp of smoke rising — that’s your cue that the pan is hot enough to sear, not steam, the vegetables. The sizzle when you add the first ingredient should be immediate and satisfying.
3. Sauté the aromatics: Toss in the diced onion and stir constantly with a wooden spoon for about two minutes. The onion should turn translucent and release a sweet, fragrant aroma. Add the minced garlic and cook for another 30 seconds, until you can smell that pungent, earthy warmth — be careful not to let it brown too much, as burnt garlic turns bitter.
4. Cook the firm vegetables: Add the bell pepper strips and julienned carrots. Spread them in a single layer and let them sit undisturbed for a minute to develop a slight char on one side. Then stir-fry vigorously for three to four minutes. The peppers should soften but still have a slight bite, and the carrots will turn a deeper orange as they cook.
5. Add the frozen vegetables: Tip in the thawed broccoli and frozen peas. Stir everything together and cook for another three minutes. The broccoli will turn a vibrant, bright green, and the peas will release a gentle steam. You should hear a steady sizzle throughout — if it goes quiet, the pan has cooled down and you need to increase the heat.
6. Create the sauce: In a small bowl, whisk together the soy sauce, toasted sesame oil, ground ginger, and black pepper. Pour this mixture over the vegetables and stir well to coat every piece. The colour of the vegetables will deepen, and a glossy sheen will appear. Let it bubble for one minute until the sauce thickens slightly and clings to the vegetables.
7. Fold in the cottage cheese: Reduce the heat to medium-low. Gently spoon the drained cottage cheese over the stir-fry and fold it in with a soft, sweeping motion. You want the cottage cheese to warm through but not break apart completely — it should remain in small, soft curds throughout the dish. After two minutes, the cottage cheese will look creamy and slightly melted, and the whole pan will smell nutty and savoury.
8. Finish and serve: Remove the pan from the heat. Sprinkle with sliced spring onions and sesame seeds. The final dish should be colourful, with pops of green, orange, red, and white. Spoon it into bowls immediately, or let it cool completely if you’re portioning it for meal prep.

Tips From My Kitchen

• Drain the cottage cheese properly: This is the single most important tip for this recipe. Cottage cheese holds a lot of watery whey, and if you add it directly to the pan, you’ll end up with a soupy, thin sauce. Draining it in a sieve for five minutes, and gently pressing with a spoon, removes that excess liquid. You’ll notice the cottage cheese becomes thicker and creamier, which means it coats the vegetables beautifully instead of pooling at the bottom of the bowl.
• Cook vegetables in batches if your pan is small: A crowded pan steams rather than stir-fries, leaving your vegetables limp and watery. If your frying pan isn’t large enough to hold all the vegetables in a single layer, cook them in two batches. The first batch will develop those lovely charred edges, and the second batch will cook faster since the pan is already hot. Trust me, this extra five minutes makes a world of difference to the final texture.
• Don’t overcook the cottage cheese: Cottage cheese isn’t like regular cheese — it doesn’t melt into a gooey mass. Instead, it softens and warms. If you cook it for too long over high heat, the curds will break down into a grainy, watery mess. Add it at the very end, off the heat if possible, and just fold it through until it’s warmed. The curds should remain distinct and soft, like little pillows of protein throughout the stir-fry.
• Batch cook for the week: This recipe doubles beautifully. I often make a double batch on Sunday evening, portion it into four airtight containers, and store it in the fridge. For lunch, I simply microwave a portion for two minutes, and it tastes freshly made. The cottage cheese does absorb some of the sauce overnight, which actually makes the stir-fry more cohesive and flavourful on day two and three.
• Freeze individual portions for later: If you’re cooking for one or two people, freeze half the batch. Portion the cooled stir-fry into freezer-safe containers, leaving a little space for expansion. When you’re ready to eat, thaw it in the fridge overnight, then reheat in a hot pan with a splash of water to loosen the sauce. The vegetables will be slightly softer after freezing, but the flavour remains vibrant and satisfying.
• Adjust the sauce to your taste: The soy sauce and sesame oil provide a savoury, nutty base, but you can easily tweak it. Add a teaspoon of chilli flakes for heat, a squeeze of lime juice for brightness, or a drizzle of honey if you prefer a touch of sweetness. I’ve made this with a tablespoon of hoisin sauce when I wanted something richer, and it worked a treat.

Equipment You’ll Need

• Large frying pan or wok (non-stick works best)
• Sharp knife and cutting board
• Fine-mesh sieve or colander
• Mixing bowls (small for sauce, medium for draining cottage cheese)
• Wooden spoon or silicone spatula
• Measuring spoons
• Airtight containers for meal prep

Delicious Variations to Try

• Spicy Version: Add one finely chopped red chilli along with the garlic, and stir in a teaspoon of sriracha or chilli oil with the soy sauce. The heat cuts through the creaminess of the cottage cheese beautifully, giving the dish a real kick. My husband, who’s usually picky, asked for seconds when I made it this way.
• Vegan Option: Replace the cottage cheese with a block of firm tofu, crumbled into bite-sized pieces. Pan-fry the tofu separately until golden and crispy, then fold it in at the end. You can also use a plant-based cream cheese thinned with a splash of plant milk to mimic the creamy texture, though the protein content will be lower.
• Different Protein: Swap the cottage cheese for halloumi cut into small cubes. Fry the halloumi in a dry pan until golden and crispy on all sides, then set aside. Add it back to the stir-fry just before serving — the salty, squeaky cheese contrasts wonderfully with the soft vegetables. This was inspired by a dish I had at a little restaurant in China that used a similar technique with local cheese.
